LNA Issue

Hi all,
In order to improve my range, I bought this week a Low Noise Amplifier SPF5189Z.
It's a 5V amplifier and I connected it to pin n°2 and 14 of my GPIO raspberry pi. Pins n° 4 and 6 are dedicated to the Fan.
When I try this following configuration, I have no signal:
Antenna - 5m SMA Cable - LNA - SMA to MCX adapter - DVB T dongle - Raspberry Pi.
Without the LNA, everything is fine with 250 messages per second.
Do you have any idea of what may be the issue ?
Thanks.

Thanks for your quick answers guys. I was not expecting a negative effect of the amplifier but it is true that around Paris I may be exposed to a lot a sources causing noise in my case.
I will try to have a look at raw signals with and without to confirm that and check the health of the component, waiting for my filter.
I will of course share the results.

To give a practical example. The Flightaware stick that I used to use had both an amplifier and a filter built in, but if I didn't add in a SAW band-pass filter I received only aircraft that were very nearby, due to overloading of the stick by cellphone and other signals. With the filter in place I was receiving in some directions to 400+ km.

By the way, your map without filter was dark with water marks "for development purposes only".
With filter it became bright, and no water marks.
Seems adding the filter has improved the map display also
